Ebook "Insects as natural enemies: A practical perspective" considerably updated and expanded version of a previous best-seller, it is an account of major aspects of the biology of predators and parasitoids, punctuated with information and advice on which experiments or observations to conduct, and how to carry them out. Guidance is provided, where necessary, on the literature that may need to be consulted on particular topics.

Ecdysis is an innate behaviour programme by which all arthropods moult their exoskeletons. The complex suite of interacting neuropeptides that orchestrate ecdysis is well studied in insects, but details of the crustacean ecdysis cassette are fragmented and our understanding of this process is comparatively crude, preventing a meaningful evolutionary comparison.

Parasitic insects are well-known biological control agents for arthropod pests worldwide. They are capable of regulating their host’s physiology, development and behaviour. However, many of the molecular mechanisms involved in host-parasitoid interaction remain unknown.

Steinernema carpocapsae is an entomopathogenic nematode that employs nictation and jumping behaviours to find potential insect hosts. Here we aimed to investigate the transcriptional basis of variant hostfinding behaviours in the infective juvenile (IJ) stage of three S. carpocapsae strains (ALL, Breton and UK1), with a focus on neuronal genes known to influence behaviour in other nematode species.

Rhodnius prolixus has become a model for revealing the molecular bases of insect sensory biology due to the publication of its genome and its well-characterized behavioural repertoire. Gene expression modulation underlies behaviour-triggering processes at peripheral and central levels.

The lack of an understanding about the genomic architecture underpinning parental behaviour in subsocial insects displaying simple parental behaviours prevents the development of a full understanding about the evolutionary origin of sociality. Lethrus apterus is one of the few insect species that has biparental care.

The evaluation study was conducted for different potato varieties and local genotypes collected from different parts of Chhattisgarh and screened against bacterial wilt and viral diseases complex. The locally collected genotypes have been further categorized on the basis of their distinct growth, yield, quality and disease and insect pest reactions behaviour. The study was carried-out at Department of Vegetable Science, IGKV, Raipur, Chhattisgarh in consecutive years i.e. 2013-14 to 2018-19.

The instintive behaviour exhibited by insects in the selecting food is always a matter of interests to entomologists, and it is one of the fundamental principles underlining the application of entomology to agriculture, horticulture and forestry. Food seclection is an important characteristic of insects that help them survive in periods with insufficient foods.

The present investigation was conducted at vegetable seed production unit, Division of vegetable Science, Shuhama campus, SKUAST-Kashmir during 2014-15 on leafy vegetables viz., knol kohl and kale crops. The pollinator fauna of both the vegetables were collected and studied for their foraging ecology and behaviour during the study period. There are various threats to pollinator diversity in modern agriculture. Our focus was to record the insect diversity under present scenario.

Global warming is a great concern throughout the world. The ill effects of global warming like change in climate, temperature, rainfall, humidity, level of carbon di-oxide has been found to have both positive and negative effects on insects, which in turn reduces the effectiveness of crop protection measures. This creates the need for global warming to be taken as an important criterion in Entomology. Being poikilothermic in nature insects are greatly affected by changing temperature.

Endophagous herbivorous insects live and feed within plants and lead to the formation of different plant architectures like galls and mines which offers protection from natural enemies. This selective feeding behaviour of the endophagous leaf miner pests is also known to alter plant physiology by manipulating the plant phytohormonal balance for exploiting the plant resources effectively. Cytokinins (CKs) are one of the phytohormones that play a key role in plant morphology, plant defense and leaf senescence.

Sorghum is an essential crop in the semi-arid tropics being attacked by nearly 150 species of insects, out of which Chilo partellus is the more devastating pest. Based on the foliar damage the resistance and susceptible genotypes of sorghum can be screened. For further understanding of the host plant resistance relationship between sorghum and stem borer the orientation behaviour and larval establishment behaviour can be studied. The host plant resistance in sorghum to C. partellus can be either morphological or biochemical.

Field experiments were conducted to record the diversity of floral visitors/pollinators in Bitter gourd Kharif season, 2018, with three replications. The experimental plot was kept free from chemical sprays during the flowering period. Insects belonging to various orders like Hymenoptera, Lepidoptera, Diptera, Hemiptera and Coleoptera were found visiting the bitter gourd flowers. Major pollinators of bitter gourd have been identified by their foraging activity. Foraging behaviour of major pollinators were recorded during different hours of the day viz. 0600 to 1800h based on No.

The newest waste management technology is bioconversion using fly larvae converting organic waste to insect larval biomass and organic residue. Bioconversion is a practice of recovering resources while simultaneously limiting the amount of organic material affecting landfill behaviour. Several organisms have been used in this treatment process. Several studies have been done using the black soldier fly larvae to degrade organic material.

Olfactory cues have a large impact on insect behaviour and fitness consequently showing potential in pest management. Yeast released volatiles are used by insects as olfactory cues for finding feeding and oviposition sites. The yeast strain SB-16-15 was isolated from spontaneous fermentation of Hippophae rhamnoides berries and identified as Pichia kudriavzevii. Thirty-nine volatiles were sampled from the headspace of P. kudriavzevii yeasts by solid phase micro extraction and identified by gas chromatography and mass spectrometry techniques.

Some say that ‘the cockroach’ will be the last species on Earth to survive. Then it has been calculated that one gravid aphid, left to reproduce with zero mortality, will, after one year, cover the globe with an aphid layer over 140 km thick. Not forgetting too, that flies and fleas vector disease. So, why should we even consider conserving insects? Quite simply, without insects, the likelihood is that the world as we know it would be radically changed in a matter of days. Besides, it is only a tiny minority of insects that harm our lives.

The ASRM meeting produced evidence that the current oversight of ART could be improved by the addition of insurance coverage for infertility treatments. Such coverage could promote the most medically appropriate procedures and reduce the incidence of multiple births with their accompanying risks and costs. Insurance coverage for infertility could also strengthen existing oversight and quality controls by requiring adherence to ASRM guidelines or performance of ART procedures only at clinics subject to SART standards.
